In the particular emlfm-humm of the invention shown, the slats l und therel'fy flash the door opening.

miami cal rods 3e be provided, 'passing through openings in the Weights. The weight o" the door preferably somewhat overbsilli-noes the Weights, sothat. when the door is down the Weight of the door itsell causes s positive pr ,ire of all the edges l?. 19 against the surfaces or' the slats, thereby insuring tight joints.

The door is adapte-d to be closed or een tended by any suitable means. :ind likewise any suitable ineens rney he provided for opening or collapsing it. In the particular construction shown means are provided for turning the pulleys sind thereh v opening or closing the door; and for this purpose gears 3G are fixed to the pnl le'vs and engaged by pinions 37 on e shaft RS extending the top of the dom-wer. t one end of this letter shaft is a sprocket or wheelv 39 oser 'which passes an endless chain l() which hangs within convenient roe-ch. .so that by pulling on one course *or other of they chain the door is either col lapsed or extended.

W'hen they-door is in collapsed condition the nested slots may he protected und coneeuled within an openhottozn @rising 5'13 et the top of the doorivev. it will he linden ystood that the rei-tical depth of. this easing ivill he. proportioned to receive all ofthe slots when the door is collapsed; out in actual prnotic-e this dept-li will not be great because of the very compact manner in which the structure may he made to collapse.

The door is held against leteralinovement and 4is guided in its vertical movements by. vertice-l members 4i :it the sides of the door oijeninff. These' members ere preferably composed of spaced :ingle-irons forming chanmiledv guides, which receive central projections on the lazy-tong linkage. `In the'peziicular construction shown in Figs. 4 end 5 these projections are formed by extensions of thepivot pins il. As shown in Fig. 5, the ends of the slats :ire recessed et 43 to receive the vertical members 4.1 and so as to form projections '+2. which engage .the sides of said members In the construction shown inF l to 6 the le fesses 43 are centrally disposed, and there are flashing extensions 42 at both sides of each guide. The said recesses are formed entirely in the portions of the slats behind the outer wall 16. so that the latter extends without opening across the front sides of the guides; und, as shown, they are preferA74 ably.. formed .in the intermediate portions l) of the slats inlernel to l'mtli Walls. lt is preferably within recesses l2-l that lne levers '20' extend new 'c the sluts. and in order to :woid the rm ity of lengthening the recesses the intermeuifio portions nl' he levers are odset as indicated at el". thus enebling the levers to he accommodated in the Fig. 3.

In order enable the bottoni sluts to loting clos. es possible to the bottoni of ine opening, :idJustnlile supporting proa -ded for the door, in the means ere nature oli plates (ses Figs. e and 7) proiided each with a vertical series of intersecting openings "lf3 for the reception of the corresponding end of the rod 26. These plates are secured rigidly to the sides of the door opening, and the intersecting openings enable e. coniiiaratively line adjustment of thelianging rod .to he effected without the use of movable parts.

Figs. 'll and' lf2-show a construction di'- 'iering from the foregoing in certain parirnlurs. The collapsible supporting con` nections are here shown in the form of a complete luzy-tong or diamond-frame link use. 'lilin linkage at erich side of the door i., composed of Crossing levers 20h, which are pivoted to euch other et their centers, es shown at 21, and et their ends to noch other and to 'the upper and lower po1- 'rions of the sluts l1 as shown at 2&3", 2?. llicpivots 21a are extended and operate in he guides 4l", which are similar to the guides 41 already described. In this consignation, it will be seen, the levers are unconnected with the slats at vtheir central pivots, and each of the levers 20 is pivoted et its ends to alte* zizi-te slats while the complementary lever 9.0.is pivot-ed at its ends to the Slat between'these two. In vtheother construction the slats themselves taire vthe piece of these levers 20". At the top the diamoi'id-freme iscoxnpleted by two short levers 24, 24:", which are pivoted at their, upper ends on the supporting rod which, 'passes through castings secured to t e narrow top sla? i2. At the 'bottom 'the di mond-frame may be similarly completed The door muy be counterweighbed und open ated in the herne manner as in the other construction. l

The construction of Figs. 'l1 and 12 also illustrates the feet that thedouble-walled door formed by the overlapping sluts may he oil center with respect"tothe linkage and the guides. This construction may he `employed when it is desired to flash the sides of the. door opening :it thel outside only. In this construction the levers of the lazy-tong linkage may he straight, since. if the sides .",xe door opening are fleshed at the outer anly the recessesin the slats through h the levers pass muy he extended :it .nier side lo nccoaniziodate straight links tr-.e door is collapsed.

dy indicated the door e r-iehetg and an in nre o. an i irirlel.- is that il with the iii-ain door, of which it forms a part. 'lhi-1 wicket is formed of the collapsihle group of short slats 11h and a short liottopi shit lil. supported by lazy-tong linkages correspond in;r to the main linkages of the door. The

linkages Cf the wicket comprise levers 20,

which are connected and sneh :is thc slidahle sockets 50 having operi ating knobs 5l 'projecting through smallj slots in the bottoni of the door.

At the top l these linkages at the sides of the wicket are preferably supported on the rod 27,;

which extends nicteil to the connterweiglits. The said rod accoriliij disposed just over the wicket door: :iii-ti another advantage ol",disposi'ng iliisl rod :it fi. distanceabove'the bottom of zii-ross the door and is vconthe door is that. it avoids-.the necessity of nirthe travel-foi'jtlie eo'unterweiglits so ,great a.`A io redini-le wells extending below the bottoni of thev door.l

AWhen the wicket is expanded and eoni .iiecicd to the bottoni rod if), or to the bot` toni ot" the main door in some other manner, ii a-'ts nioi'ely as part of the main door. lts iii-dinges being in alinenient with \tlie inain lini'ages, its slats more in exactly the same Q manner as the slats of the iii-.iin door with which tlici-Y :ire 'aline-d. has been shown severed, Ait will be niiderstood that it might extend all the way across the door in onf,x piece. suitable provision beg ingr made for fastening the bottoni of the j wicket theicto. When it is desired to.open the niclret only, the catches at the bottoni the sides of the wicket-door opening in the main door. To this end the slats 11", lil* are provided at the ends with projections wliich extend over the adjacent ends of the severed slats of the main door. T hose projections continuously overlap each other Vwhen the door is down, so as to leave no opening for admission of heat or the weather. It will be understood that these (lashing projections are formediin the same manner as the flashing projections 42, that is to say, by cutting out or recessing the ends of the ii'icket-door slats.

From the foregoing description the genera operation ot the door will be readily iiin'lerstood. 'lien closed it is doublen'alled throughout, containing an air space which prevents the transmission of great heat from one side to the other. When raised or collapsed it nests automatically .i acting` independently of the main indicated in Fig. 1 the slats i door either open or in a Ventilating condiin a compact manner at the top 0l' at one side of the opening. At the side next toY the weather. and in fact at both the inner and outer sides, the door is entirely selfflashing, and this flashing is of a veryieffective character hecause the weight of the door itself causes the edges and faces of the slats to contact with a positive pressure. The degree ol this pressure may be varied b v iarying the ainonnt of counterwcighting. The door :i'ords a practically imperrioiis protection against eren a driving rain, because the water would have to make its 'way through tight joints at the oiiterside, then pass upward between the Walls of the door, only to encounter another set of tight joints at the inner sideof the door. Even a stre-.iin lfrom a hose ,would be unable to Ict thririigh the door. In addition to its fire anilweather-proof qualities, the door has the advantages of being entirely accessible for painting, inspection and repair and oi' making it possible to remove and replace a shit when necessary with expedition and convenience. The door also lends itself to Ventilating purposes. Thus, as indicated in Fig. 9, the door may be slightly raised. when all theslats swing away from cach other siitlicieiitly to give a loiivered effect by partially opening the doorway. The extent of the ventilation openings is readily. adjistiible, and eren a very slight movement of the door alfords some ventilation. The

. door may be held at any height by the coun while the rod 15) tcrweights assisted by the friction of the pulleys, gears, etc.; or if li'tis desired to have the door decidedly ote'rbalanee the weights, or if there are no weights, any snit.;`- able derives may be provided for holding the g tlCn. :irc i'clcascfl and the wicket is raised, its;

It will be understood that the invention is not limit-ed to details and that numerous changes may be made withoiit departing l'roni its scope. It will be apparent that those slats which serve as parts of the'lazy tong linkage may be reinforced if desired. lt will also be obi-'ions that the idoor or shutter may be arranged to operate sidewise across the door or window opening, instead of being raised and lowered, that is to say, the slats may be approximately vertical iiisteail of horizontal.

Fig. al indicates the fact that the structure may be operated by a fusible link, so that the door is released to close the door or window o suingr by its own weight, or by other siiitab e means, in case of lire or of dangeroiisly high temperature. To this end a fusible link or section is shown at .35 in the cable 32. It will he understood that this fusible section is duplicated in the cable at the opposite margin of the door or window opening (not shown in this View) and that when these links are fused the door or shutter is 13o free to ilesvend of its own weight. f the fusible links uie intm'pnsml in the Connectiafm LPM-ven liv ruiluusililn ati'uctuza und the ununtci\\;ij "li 1, (where cnuntvrweights are cniplnyml) i' .i ing of the.x links frues the strnvtm'e nl' [new weights. so tliut it (1105435 iustnntuiwuubly.
